positional arguments:
  project        name of project whose dependencies (or dependents) to show

optional arguments:
  -h, --help     show this help message and exit
  --version      show program's version number and exit
  -r, --reverse  show dependent projects instead of dependencies
  -f, --flat     show flat list instead of tree

6 Hacking

This project makes extensive use of tox, pytest, and GNU Make.

6.1 Development environment

Use following command to create a Python virtual environment with all necessary dependencies:

tox --recreate -e develop

This creates a Python virtual environment in the .tox/develop directory. It can be activated with the following command:

. .tox/develop/bin/activate

6.2 Run test suite

In a Python virtual environment run the following command:

make review

Outside of a Python virtual environment run the following command:

tox --recreate

6.3 Build and package

In a Python virtual environment run the following command:

make package

Outside of a Python virtual environment run the following command:

tox --recreate -e package
